| Sony | KV27XBR10 | IC-51 HAS THE WRONG PART DESCRIPTION, SEE SUPPLEMENT # 4 | Service manual indicates part as BX-1393 (8-749-900-36).Servicer finds this part will not fit. Actual part in unit is CBX-1618-51(8-741-100-62). Has there been a production change? -HQ COMMENTS: Your servicer is correct. Tokyo is issuing a ServiceMan | ||
| Sony | GENERAL | INDICATION OF COMPONENT LOCATION ON FPRS | It is frustrating not being able to quickly locate a componentlisted in a field problem report. Since the report only describes thereference, number a tech still has to spend time to locate the componenton the schematic or the board. -HQ COMMENTS: This | ||
| Sony | CCDF55 | WHITE BALANCE ADJUSTMENTS | When doing the white balance adjustment in this unit (not thepreset adjustment), be sure to use the C14 color filter. | ||
